Abstract

For connecting a PV array (2) via an inverter (3) to an AC power grid (4), at first a DC link (7) at the input side of the inverter (3) is pre-charged from the AC power grid (4). A link voltage of the DC link (7) is adjusted to a pre-set value with the inverter (3) connected to the AC power grid (4), the pre-set value being lower than an open circuit voltage of the PV array (2), and then the PV array (2) at its open circuit voltage is directly connected to the DC link (7), while the link voltage is continuously adjusted to the pre-set value.
